jr - that it was in 106 degree weather with a DA over 3600, dirty air filter and crap 91 gas!! Gonna re-dyno it in December with better gas.

The L99s give to LS3s in several ways:
1) Lower compression
2) More drive train loss - about an extra 5%.
3) Possibly a smaller cam due to the AFM - not positive on that.

But we do love the much broader torque curve from the VVT
